With the wide application of Android system, a single screen support can not meet the needs of every field, especially the current hot intelligent terminal, which generally needs two screens to support. We often see in office buildings, shopping malls, elevators and other occasions that some advertising machines mostly display the same picture on two screens, which belongs to double screen display, while some pictures with different display on two screens are double screen display.
Dual screen display is widely used in smart self-service terminals. This technology refers to the realization of driving two LCD screens at the same time on the same software and hardware platform, and the contents displayed on these two screens can be different. In addition, another application direction of dual screen display is the order cash register. The main screen realizes the order settlement, while the secondary screen displays the consumption information and payment information.
At present, the cost-effective dual screen display Android motherboard solutions are mainly rk3288 and rk3399. Then, how to set up dual screen display?
At present, the cost-effective dual screen display Android motherboard solutions are mainly rk3288 and rk3399. Then, how to set up dual screen display? With more than ten years of technology research and development experience, jinhaituang has created a number of rk3288 and rk3399 series Android motherboards, which support dual screen display, can interact with each other, and can connect their own systems in various fields. Usually, some standard mainboards support dual screen display by default. If you need to set dual screen display, you need to configure the screen parameters. After completing the screen parameter configuration, install the dual screen display test demo.
Rk3288 dual screen display
If it is the dual screen display of lvds/hdmi/edp, you can choose rk3288 series, which supports any combination of two out of three to achieve dual screen display
Jhc-886 super dual screen and highly integrated motherboard developed by Jinhai Chuang is based on Ruixin micro rk3288 core chip platform, equipped with a new quad core cortex-a17 scheme, high-end processor GPU mail-t764, the maximum configuration of memory DDR3 4G, and the maximum support of 64g storage capacity. The built-in multi-threaded operation processing ability and high-performance core configuration can realize the development of a variety of intelligent technology functions.
It has rich interfaces, supports dual output of EDP and LVDS interfaces, adapts to different display screens, supports the current mainstream resolution, and can realize 4k*2k HD display. At the same time, it is equipped with different types of signal output, which can be matched arbitrarily, so as to easily realize the double screen abnormal display scene, and provide more selectivity for advertising business display and intelligent terminal, so as to greatly save the cost of hardware equipment.
RK3399Dual screen easy display
If it is the dual screen display of lvds/hdmi/mipi, you can choose rk3399 series, which supports any combination of two out of three to achieve dual screen display
Jhc-991 is a classic general-purpose motherboard, which adopts Ruixin micro rk3399 chip, dual cortex-a72 large core + four cortex-a53 small core structure, high-end processor GPU mail-t860, the main frequency is up to 2GHz, the maximum optional Samsung 64g EMMC, built-in multiple high-performance hardware processing engines, safe, stable and low-power consumption, and gives full play to both kernel performance and user experience.
With EDP, Mipi, HDMI and other display interfaces, it supports LVDS interface dual output and can adapt to different display screens. It supports high-definition 4K output and H.264 decoding. The display screen is first-class, enjoying a high-end and realistic visual feast. At the same time, it can also be equipped with V by one 4K dot screen. This motherboard supports dual screen display function, which is especially suitable for dual screen cash registers, commercial display advertising machines and self-service retail terminals.
The realization of dual screen display function can not only help users reduce the cost of hardware equipment, but also help improve the interactivity of consumption scenarios. It is particularly simple for installation and deployment and saves space.
